,ROLLER FOR CONVEYEB$.

Application filed Ju1y 1'5, 1926. Serial No. 122,653.

: This invention relates to conveyers such as are used for carryingarticles from one place in a building to another and which comprises arunway of free rotating rollers and it consists of means self containedwith each roller for retarding the momentum of the roller and preventingidle spinning or rotating thereof.

The invention consists in the novel features and in the combinations andconstructions hereinafter set fort-hand claimed.

In describing this invention reference is had to the accompanyingdrawings in which like characters designate corresponding parts in allthe views. a

Figure 1 is a fragmentary perspective view of a conveyer embodying myinvention.

Figure 2 is an elevation, partly broken away, and partly in section, ofone of the rollers.

Figure 3 is a cross sectional view through one of the rollers.

Figure 4 is a perspective view of a modified form of a conveyerembodying my invention.

Figure 5 is a view similar to Figure 2 of a form of a roller shown inFigure 4.

Figure 6 is a detail view of the means for stopping the momentum of theroller shown in Figure 5.

As is well known to those skilled in the art, I

in carriers embodying rollers, the rollers after an article has passedover them continue to roll or rotate so that the succeeding articles arepassed along faster than and collide with the articles in front, andthis happens whether or not the carrier is inclined or some of theroller-s are power driven.

In some conveyers, attempts have been overcome to prevent theacceleration ofthe movement of the articles by connecting up rollers atintervals with power or by putting various forms of friction brakes. onthe V rollers.

Neither of the foregoing ways of retarding the momentum of the rollersis entirely satisfactory. v.

\ My invention consists of which the rollers have self contained meansfor retarding their momentum.

a conveyer in In the drawings, 1 designates the frame of the generaltype of conveyer embodying my invention, and 2 is the seriesof rollers,the v rollers being here shown as mounted on axles 3 supported in theframe 1. The axles are stationary and anti-friction bearings areinterposed between the heads at opposite ends of the rollersand theaxles 3. The axles arehere shown as mounted'in slots 5 in the frame 1and hence capable of a sliding move ment lengthwise of the conveyer.

.The means for preventing or retarding the momentum of the rollercomprises an eccentric weight fixed wi being designated 7and preferablyextending the length of the roller. Obviously, the weight inside of theroller will always tend to hold the roller so that the weight is belowthe axes of the roller and hence to retard the momentum or stop therotation of the roller after the article being conveyed has passed overthe roller, article causes the roller to rotate.

In Figures 4, 5 and 6, a modified form of such momentum retarding meansis shown" in which the weight 8 for retarding the momentum of the rolleris carried by an arm 9 mounted on the axle 10, the axle 10 and theroller '11 being rotatable as a unit.

In this form of my invention, anti-friction bearings 12 are interposedbetween the axle" 10-and the frame 13 of'the conveyer. Also,

In testimony whereof, I have hereunto signed my name, at Syracuse, 1nthe county thin the roller, this weight it being understood that such 7of Onondaga, and State of New Yorln this j 1st day of May, 1926.
